When articles are sold in, packages, it is now "customary to pack 1n thecontainers *therefona definite number of the individual articles."'Dilficulty is experienced inpacking precisely the s'ame number indlflerent con'tainersifftheParticles are measured by weighing them Bymeans of my improved" machine, however, the number of crown caps or likearticles to be inserted in thepackage 7 can be" counted with accuracyand the carton or container'therefor can be quickly and-easi ly filledinvariably with the correct number of thearticles by unskilled andinexperienced wh n.

"In thepractical embodimentofmy inven 'tion, thecrown caps 10 arefed toa, hopper 11 of the usual type, which is operatively con nected toa'suitable agitator 12. The agita: tor serves to align and to feed thecaps in a single rowand .in the proper positions to a chute-1-3, and maylibeoperated in the usual fmanner, as by means of the belt 14 driven by"a suitable source of power, not shown, and rotating the pulley 15,mounted on the agitaf torshaft.

' The chute 13' is formed with the cap passage .16 and may consist ofthe rear plate 17, the spacers 18 and the'front plates 19", all suit"'janismand the support for the containerto ably secured together as bymeans of the screws 20. Below the lower end 21 of the chute is arrangeda table 54 of a height convenient to the operator. The chute is made ofsulficient length to align therein at least the number of crown capsrequired to be inserted inthe smallest carton 22. It will be 7understood that the chute is substantially upright so that the caps maypass out therefrom by gravity when allowed to do so.

Stop means are provided to maintain thecaps in the chute until a minimumpredetermined number has accumulated therein, and

to release an unvarying number of said caps ,toallow said caps to dropinto a carton 22 at the will of the operator. Said stop means includesastop finger 23adapted to engage a capnear the upper end of the chute anda stop hook 24 adapted to enter the cap passage 16 and to be interposedbetween the low ermost cap in the chute and the end of the chute,together with suitable mechanism for operating the finger and the stop.The stop 24 is formed with a hook end 25 sufficiently thinto passbetween the front plates 19 of the chute and into engagement with thefront surface of the rear plate 17. The bearing brackets 26 secured tothe chute as by means of suitable screws 27 serve as supports for therock shaft 28, on which the stop 24 is supported. The lever 29 is alsosecured to the rock shaft28 and is connected at one end with the linkrod and at its other end to the connecting link 31, a tension spring 32acting on the lever 29 to maintain'the stop 24 nor- [mally in operativeposition. The lower end of the link rod 30 is secured to the treadle 33,pivoted at 34, so thatfoot pressure on the treadle pulls the link rod 30and the lever 29 downwardly against the action of the spring 32 andmoves the hook 25 out of the chute, thereby releasing the row of capsand allowing them to drop out of the chute.

The upper end 35 of the upright connecting link 31 is secured to thecrank 86, which is mountedon the shaft 37, rotatably supported in thebearings 38. On said shaft 37, is fixed the crank arm 39 terminating inthe plunger 40 which is inserted into the bore 41 of the finger 23. Apin 42 on said plunger 40 operon the mechanism avoided. The crankarm 39and the finger 23 secured thereto may be mounted on the shaft 37 toproject in substantially the reverse direction to that in which the stop24 projects from its shaft 28, so that when the treadle33 is operated towithdraw the stop 24 from the chute to release the row of caps thefinger 23 is caused simultaneously to enter the chute and engage.

the cap .adjacent thereto. Similarly, when the treadle is released, andthe hook end 25 of the stop24 enters the chute under the infiuence ofthe spring-32, and stops the discharge of the caps from the chute) thefinger 23 is withdrawn and allows the caps tofall into contact with eachother in a row, filling up and accumulating in the chute above the stop24. If the chute is designed for a four dozen carton, the finger 23 andthe stop 24 are spaced apart a distance equal to slightly more than thecombined diameters of fortyeight caps. The forty-ninth cap in the rowcounting up from the bottom, free of the finger 23, the row beingsupported by the stop 24.

. On the operation of the treadle, the stop 24 being withdrawn, thefinger 23 engages the forty-ninth cap in the row and prevents that captogether with the caps thereabove from passing through the chute andintothe versed, whereby the row of caps accumulate above the stop'24 readyfor delivery into the next carton.

It will be understood that, if desired, the crank arm 39 and the stop 24may be mounted on'the same or corresponding sides of their respectiveshafts'and thatthe relative reversal in operation may be efiected bysecuring the lower end of the connecting link 31 to the left end of thelever 29 as viewed in Fig. 1 in a manner which will'be obvious. If thecartons are to be filled with larger numbers of caps, such as eight ortwelve dozen, a multiplicity of identical chutes and connectingmechanisms may be provided. In Fig. 2, I have illustratedtwo additionalchutes 46 and 47 arranged at an angle so that their respective lowerextremities49 and 50 are spaced apart a'distance less than the size ofthe carton adapted to hold a gross of caps. The shafts 28 on the alignedchutes 49 and 50 may be removably coupled together by means of anysuitable shaft coupling and an additional removable rod link 30connected from the treadle 33 to the lever 29 is normally I of either ofthe chutes 49 and 50. The operator, to fill the largest size carton,need then only press the treadle which, with the connection ustdescribed, operates all the chutes in unison. To fill the carton witheight dozen caps, the link rod 30 to one of the chutes need merely bedisconnected, and the treadle operativelyconnected to only two of theshafts 28 as above described, whereby operation of the treadle releasesthe four dozen caps in each of the two chutes simultaneously. i

It will be understood that where a multiplicity of chutes 'is'used, thechutes may be advantageously emptied 1n succession, when ,filling eventhe smaller, size carton, since timeis thereby allowed'for the emptiedchute to be again filled before'its turn comes to be falling within thespirit and scope of my in? V 1 vention and within the range ofequivalents afforded by the appended claims. 1
